Turbine component for, e.g. gas turbine used in gas-fired power plant, comprises end hole formed perpendicular to guide bore which is formed vertical to edge portion to form breaking point between inner wall of guide bore and flat side

摘要

The turbine component comprises a guide bore having inner wall, which is formed vertical to an edge portion (6) to form a predetermined breaking point (17) between the inner wall and flat side (5). An end hole (9) is formed perpendicular to the guide bore. The diameter of the guide bore is larger than the diameter of the end hole. A seal element is provided in the guide bore.
